Yes, the diagonal was in. It’s a William Optics dielectric. Good idea about the extender. However, I’ll have to raise the tripod a tad to use something that extends straight back or I’ll be on my knees trying to focus if Sun’s altitude is very high. The camera’s viewing screen is too small to see any detail for the focusing step. However, I could link the camera to an old TV with the camera’s AV connection and view that image to focus the shot. I think I’ll try that, tomorrow. Wouldn’t want to stress myself, today. Thanks, Joe. Dave On May 6, 2012, at 6:07 PM, Joe Bauman wrote:
Nice job. So this was taken with the diagonal in? I suspect that if you could eliminate the diagonal -- i.e., use a longer tube in its place -- the view would be even more spectacular. Every unnecessary glass surface between you and the sun, such as the diagonal's mirror, degrades the image somewhat. Best wishes, Joe

Joe,
I shot it with an ETX-LS 6” ACF with a 40mm lens attached to a Nikon Coolpix 4500 digital camera with an attached bulb. The 40mm lens was attached to the camera lens with an adapter I purchased from ScopeTronix. I put the lens into the scope‘s diagonal, got as good a focus as I could, took the lens out, threaded it to the camera then put the lens/camera back into the diagonal. I waited for the vibrations to subside, then took the shots. If it was any more complicated than that I couldn’t have done it. This is what I plan to use to take the photos for the upcoming annular and transit. Let’s hope it’s clear skies.

OK, Steve, let’s try this, again. This from a guy who can, barely, operate a TV remote.
